As of May 24, 2026, the tunnel is closed. The alternative route is by road to the village of Leitza. From there, you take the greenway again.

At this point, you can see the remains of wood used by the aizkolaris (axe-wielding log cutters). There is also a statue honoring the aizkolari women, with a text on its back in Basque that means "Women have always cut wood."

Great route for beginners as has mainly constant and light slopes. Only half a dozen uphills the first 30 km from Pamplona.

Scene of a famous battle, in the middle of a large field and surrounded by a herd of horses.

That bridge is called "INTUIA-ko zubia" the INTUIA farmhouse is next to it. The misnamed "witches' bridge" is called UNANIBI-ko zubia, right in the Otita park (beginning of the Leitzaran valley). Don't forget to bring lights to cross the numerous tunnels in this valley!! Not to see but to be seen.

Great tour always along the river and through countless tunnels. Also recommended in hot weather. Bring light if possible.
